EXPERIMENT NO: 5

Aim:-Introduction to preparatory 'G' and 'M' function for CNC machine.

G - Codes: -

GOO- Rapid Movement.GOO causes linear motion to give position at maximum federatefrom current position i.e. predefined in option file. e.g.G00*0.0

G01 -Linear InterpolationG01 causes linear motion to give position at the last specified feed rate fromcurrent position, e.g. G01* 30.0 Z1.0F100.0

G01 - Circular InterpolationG02 causes a counter clockwise arc to the specified position.e.g. G02*30. Z15.0 RS.0

G03 -Circular InterpolationG03 causes a counter clockwise arc to the specified position.e.g. G03*30.0 Z15.0 R5.0

G04 -Dwell TimeG04 causes the program to wait for a specified amount of time.e.g, G04*1.5 .

G20 -inches Data InputG20 causes position to interpreted as being in imperial units.

G21- Metric Data InputG21 causes positions to interpret as being in Metric unitsG28 -Go to Reference PointG28 causes a fast transverse to the specified position and thento machine datum.

G40- Tool Nose Radius Compensation CancelG40 cancel tool nose radius compensation

G41- Tool Nose Radius Compensation left.G41 enables tool nose radius compensation to left programmedPath

CAD CAM 651

G42- Tool Nose Radius Compensation right.G42 enables tool nose radius compensation to right programmedPath

G70 - Finishing CycleG70 causes a range of blocks to execute then control passes toblock after G70 e.g. G70 P10 Q20Where, 'P' -1st Block of cycle and 'Q' -Last block of cycle

G71 - Multiple Turning CycleG71 causes profile to be roughed out by turning. e.g.G7l UO.SR1.0 where,`U’ -Depth of cut in mm and 'R' -Retardation amount in mm

G72 - Multiple Facing CycleIts causes the profile to be roughed by facing.e.g. G72 WO.S R1.O and G72 P10 Q20 U0.1 W0.1 F45.0Where, 'w' -Depth of cut in each pass in Z- axis and 'R' - Retardation amount in mm.

G73 - Pattern Repeating CycleIt causes the profile to be roughed out by displacing the profile.e.g, G73 U3.0 W0.0 R5Where 'u' -Distance and Direction of relief amount in x- axis radius designation & 'R' - No. of passes.

G74 . Peck Drilling CvdeG74 is a Z axis pecking. cycle .e.g.G74 R1.0 and G74 Z40.0Q1000 F30Where 'R' - Retardation amount in mm. 'Z' -Deptn ot cut in Z- Direction inmicron. And 'F' -Feed rate.

G76 - Multiple Threading CycleIt is a multiple pass threading cycle, e.g. G76 P03156050R0.02 and G76 X17.9 Z50 P919 Q100 F15Where, the 'P' value is 03 number of finishing Passes15 Put out angle60- Angle of threadingThe `o’ IS the depth of cut in micron and the `R’ is the finishing allowance in mm.

CAD CAM 651

G90 - Turning CycleG90 is the diameter cutting cycle .e.g. G90 00700020

G92 -Threading CycleG92 performs one threading pass.

G94 - Facing CycleIt is an end face cutting cycle, e.g. G94*00z0.0F20

G98- Feed Pre Minute

It sets the feed per minute mode e.g.G98

M codes:-

M00- Program StopCycle operation is stopped after a block. M00 is executed.

M01 - Optional StopCycle operation is stopped after a block. M01 is executed.

M02 - Program EndStop the spindle. turns coolant off e.g. M02

M03 - Spindle Forward Starts the spindle spinning forward at the last specified spindleRate, e.g. M03S1200.

M04 - Spindle ReverseStart spindle reversed spinning at the last specified spindle rate.E.g. M04 S1200.

M05 - Stop spindleStop the spindle without changing the spindle speed e.g. .M05

M06 - Tool Change 'The 'T' prefix causes a tool change, It need not be: paired with anM06- E.g. M06 T0200

M08-Coolant OnM08 turns the coolant on.

M09- Coolant OffM09 turns the coolant of f .

CAD CAM 651

M10-Chuck OpenM10 -Opens the chuck.

M 11 - Chuck CloseM11- closes the chuck.

M30 - Program Stop and RewindStops the spindle turns the coolant off

M38 - Door OpenOpen the door Waiting unit the door is open

M39- Door Close

Close the door, waiting until the door is closed

M98 - Sub - Program CallM98 causes another program to be executed .e.g. M98 P000

M99 - Sub - Program ExitReturns control to program that called the current program
